Semawise tools

Quick answers to the numbers questions

Small, free, plain-English calculators for the practical semaglutide questions that come up a lot — what it costs, and how the math on a compounded vial works. Each one runs entirely in your browser, stores nothing, and is built to inform, not to advise.

These tools are educational, not medical or financial advice, and never a dose recommendation. Prices and programs change; compounded products vary. Verify every figure with your prescriber, pharmacy, and insurer before you budget, buy, or inject.

Weight-loss projection

How much might I lose on Wegovy?

Wegovy weight-loss projection calculator

Enter your current weight to project where you might be at ~68 weeks on semaglutide 2.4 mg, using the STEP-1 trial average (−14.9%), plus a milestone trajectory across the 16-week titration. A population average, not a promise.

Project my weight loss Cost estimator

What will it actually cost me each month?

Wegovy & Ozempic cost calculator

Pick a product and how you're paying — savings card, NovoCare self-pay, or list price — then add any telehealth membership fee to see an honest monthly and annual out-of-pocket estimate.

Estimate my cost Unit converter

How many units is my compounded dose?

Semaglutide dose ↔ units converter

For compounded multi-dose vials: enter the vial strength and the water added, and convert a dose in milligrams to units on a U-100 insulin syringe (and back). A math converter — not a dose recommendation.
